PLATFORM ATTACHll/LENT FOR WINDOWS.

Applicationfiled April 4, 1923. Serial No. 629,864.

T 0 all whom it may concern:

Be it known that I, ANTON NELS N, a citizen of the United States, andresident of Saul; Center, in the county of Stearns and State ofMinnesota, have invented certain new and useful Improvements in PlatformAttachments for Windows, of which the following is a specification.v

M invention relates to improvementsin plat orm attachments for windows,and itconsists in the combinations, constructions and arrangementsherein described and claimed. l

An object of the invention is to provide a device of simplifiedconstruction which is adapted to be detachably secured to the frame ofawindow ina building an'd which affords facilities for supporting aperson in a. relatively elevated position ,exteriorly of the buildingfor the purpose of cleaning, or repairing-the window or for any otherpurpose.

A further object of the invention, is to provide an attachment of thecharacter described which is adapted to be adjusted'for application towindows of different widths within a considerable range of sizes.

A still further obj ectof the inventioiris to provide an attachment of,thecha-racter described which can be conveniently and easilyjattachedto or detached from a window without the use of anyspecial tools, and

vwhichis adapted to be folded or collapsed into small compass forthepurpose of transportation or storage.

Astillfurther object of the-invention is .to provide an-attachnientofthe character 'descri'becl which is relatively safe when in use andembodies means tending to prevent any person supported thereon fromaccidental displacement therefrom.

Other objects and advantages will be ap parent from the followingdescription,,considere'd conjunction with the accompanying drawings, inwhich- Figure 1 is a perspective View showing a practicalembod1ment ofthe invention in applied position on the frame of awindow, the; lowersash of the window and portions 1 of the supportingstructure thereforbeing shown lll'VGllZl'CiLl SQQtlOIl; I

t Figure 2- s abottom plan VIEW, of frag -mentary portion of the devicein detached position, and

Figured: is aside elevation of a fragmen- '-tary' po rtion of the.device detached In carrying out my lIlVGlltl0I1,I provide asubstantially flat base or platform designated generally 1 which maycomprise a: pair of similar transverse sections 2 and 3 respec tivelyarranged in juxtaposed adjacent relation and hingedly connected togetherat their adjacent edges, as indicated at at. The sections 2 and3 whichmay be boards are normally held in extended or outwardly swung positionin respect to each other or in other words insuch position as to lie inthe same plane by a pair of bars 5 which extend longitudinally: of theplatform. at predetermined distances from the side edges ends of thesections Qan'd 3 and which are secured to the respective sections 2 and:3 by boltsiandnuts 6. The bars 5 are spaced from the under sides ofthesection's 2 and by spacingand stifiening blocks 7 and 81espectivelythrough "which the bolts extend, the strips 7 and 8 atcorrespon'dingendsof the sections 2 and?) being disposed in align- 1113 With'eachotherwiththe adjacent ends thereof spaced slightly and beveled oppositely asindicated f and 8 respectively so-jithat the adjacent, endsof alignedStIiiPS 7 and "8 divergeto'ward their lower sic es. V

The sections 2 and 3 ofthetplatforin have spaced apart series of boltreceiving open ingsformed therein to extend longitudinall y thereof asindicated at 9" and the respective aforesaid bolts {may be projectedthrough the bolt receiving; openings 9; of the several series'selectively sons to vary the, spacing of t lie bars fiffrom" the'sitlespf the platform tions 2 and V3 and ,thatthe latter may then befolded to lie flatwise one uponithe other and to thus occupy butrelatively small ofthe platform orin other words from the i space, assumng of coursethat the'hereinafter described superstructure, on theplatform "has first been removed. I

The bars 5 constitute the horizontal members of brackets for, engagingwith t-he sills 10 of window frames,andiwiththe outer faces of avertical wall llffor, the purpose of attaching the, platform to a.window sill and for, supporting the. platform. in a position in. whichpartly disposedg upon the-win llO dow,-sill, and extending beyond J theouter end to provide a pair of spaced apart axially alignedsleeveportions 18 adapted to receive therebetween a sleeve portion 14 formedatone end of each of a pair of bars 15, the

respective sleeves '13 of the two bars 5 be ing axially aligned and thesleeves 1 f being arranged in register with the sleeves 13 so that eachbar 15 will be hingedly attached to the corresponding bar 5 when a rod16 is arranged to extend through all of said aligned sleeves. Cotterpins 17 are extended through transverse openings in the extendingextreme end portions of the rod 16 to prevent such axial movement of thelatter as would result in its moving out of engagement with the sleeveportions of the two bars 5. Each bar 15 constitutes the second member ofeach of the pair of brackets provided for the purpose hereinbeforesetout. The bars 15 are connected at their free ends'by a'rod .18whichextendsslidably through alignedsleeve portions 19 formed at thefree ends of the bars 15 and which is prevented from disengaging thesleeve portions 19 cotter pins 20 engaged with the extending extreme endportions thereof.

The bars Shave tongue portions 2lstruck upwardly therefrom in positionto enter the 7 space between the diverging ends of p the pairs ofspacing and reinforcing strips 7 and 8. These tongue portions arebent-to provlde axially aligned sleeves22 through which a rod 23extends, The extending extreme end portions of the rod 23 also areprovid'edwith cotter pins 9A for holding the rod against such axialmovement as would result in its disengaging th'e s'leeves The, hookportions 12 are fashioned at their free ends to provide aligned sleeves2 f through which a rod 25' extends, the latter 'being held from movingout of'engagement with the sleeves 24 by cotterpins 26 engaged with theextending extreme end portions thereof; a l. a v

l/Vith the arrangement described, the

corresponding members ofuthe two brackets are securely stayed toeachother. The

brackets-canbe slid on the rods 16, '18, 23 i and 25 when detached'from'the sections 2 and 3 of the platform to permit adjustment of thebrackets inrespect'to each other for engagement with'the sills ofwindows of different widths, the brackets being held by the platformwill be firmly stayed to the wall and thus braced at its outer ends.-

A superstructure on the platform serves to shield personssupported onthe platform from the gaze of persons adjacent to the building and alsoprotects the occupants of the platform from the wind. Thissuperstructure comprises a guard frame including standards 28 and 29respectivelyfat the outer corners of th s platform and other standards30 and 31 respectively upstanding from points adjacent to the side edgesof the platform and at appreciable distances from the inner end of theplatfo-rms'being located a distance from the innerend of the platformsufficient to permit the lower sash 32 of the window to be closed andwhen in closed position to lie in a verticalplane lo,- cated between theplane of the inner end of the platform and that of the standards .30 and31'. The standards 29 and 31are connected and'stayed together at pointsadj acent to their upper and lowerends by transverse connectors 83 and3t'respectively.

Similarconnectors 85 and 36 respectively connect the standards 28 and 30adjacent Still other horizontal connectors 37 and 38 respectivelyconnect the standards 28 and 29 at points to their upper and lower ends.

adj acen-t totheir upper and lower ends. With this arrangement a stableframe structure other suitable fastening means to certain or all oftheframe members leaving the upper and inner side of the frame-structureopen so that a person may have accessto the platform through the windowand when on the platform may move freely without his movements beingretarded the guard provided this framestructure preferably being closedat thesides and outer end by 'a fabric 39 secured by stitching 4:0 orany U-shaped frame 42 having the arms thereof fashioned "at-their freeends to provide eyelets through which 'a rod 44 extending horizontallybetween the standards 28 and 30' at points intermediate the upper and.

lower ends of the latter extend, the U shaped s frame 42 having a stripof fabric arranged in spanning relation to the arms and being secured tothe latter by rows of stitching as or the like. The fabric 45constitutes the article supporting member of the shelf and the lattermay be releasably held in a horizontal position by hanger arms 47swingingly attached at their upper ends to the transverse connector 35and having hook portions 48 at their lower ends adapted for engagementwith the web portion of the U-shaped frame. .When not in use, the hangerarms 47 may be disengaged from the frame 42 and the shelf may then beswung downwardly into vertical and out of the way position. I

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. The device is simple inconstruction and can be readily attached to and detached from the sillof a window frame of ordinary construction without the use of any too-lsand without any changes in the construction ofthe window frame beingrequired. lVhen detached from the window frame, the device can bedisassembled and the parts thereof packed to take up but relativelylittle space.

WVhile I have described the attachment as being adapted for the use of aperson engaged in the work of cleaning or rep-airing windows, yet itwill be apparent that the device is capable of other uses. For example,the platform 1 may be of sufficient area to permit of a bed, beingsupported thereon for the use of invalids and others who desire to sleepout of doors. The guard structure would protect such person from thegaze of persons e-Xteriorly of th building and also would affordprotection from the wind.

Obviously, my invention is susceptible of embodiment in formsv otherthan that illustrated in the accompanying drawings and I thereforeconsider as my own all modifications and adaptations of the form of thedevice herein described which fairly fall within the scope of theappended claim.

I claim;:- A device of the character described comprising a platformadapted to be'partially disposed upon the sill of a window frame and'toextend beyond the outer edge of the latter, means carried by theplatform for engaging with the window sill and with the outer face of awall provided with the window sill for holding said'platform in theaforesaid posit-ion in respect to the window sill, a superstructureonthe platform having portions upstanding from the sides and outer endof the platform, and a shelf swingably supported on the superstructure,said shelf being foldablevfrom horizontal posi tion to a position inwhich it is disposed flatwise against one of said upstanding portions ofthe superstructure.
